Special Issue Information

Dear Colleagues,

We invite researchers to submit original innovative research and reviews to this Special Issue on "Diamond-Like Carbon and Diamond-Like Carbon-Based Nanocomposites". This Special Issue incorporates many of the important aspects of the growth, characterization and application of diamond-like carbon (DLC) and DLC-based nanocomposites.

Even though the history of amorphous carbon spans for already 65 years from the first publication, the interest in the development of this field is not decreasing. Carbon based amorphous films (or diamond like carbon (DLC)) are widely investigated because of the attractive properties it shows: high hardness, chemical inertness, tunable electrical resistivity and optical properties, biocompatibility. The incorporation of metal and non-metal elements into carbon or hydrogenated carbon matrix opens up new fields of application. DLC with metal inclusions can show interesting piezoresistive effects, plasmonic and antimicrobial behaviour.

The aim of this Special Issue is to highlight some of the most recent and significant contributions to the diamond-like carbon and DLC-based nanocomposites field, through a combination of original research papers and review articles from leading groups around the world.

In particular, the topics of interest include, but are not limited to:

  • Deposition methods of diamond like carbon and DLC based nanocomposites;
  • Theoretical and experimental studies addressing deposition-structure-properties relationship;
  • Surface patterning of DLC and DLC based nanocomposites;
  • Tribological, optical, antibacterial properties of the DLC and DLC based nanocomposites;
  • Applications of DLC and DLC based nanocomposites in the area of optics, medicine, sensors, etc.

Nonlinear optical properties (self-saturable absorption and reverse-saturable absorption) of diamond-like carbon films with variable amounts of embedded copper nanoparticle (DLC:Cu) films deposited by high power pulse magnetron sputtering were studied in dependence on deposition conditions. X-ray photoelectron spectroscopy was used to study elemental composition and He ion microscopy to study changes of the size, shape, and concentration of the Cu nanoparticles deposited using different pulse currents as well as argon and acetylene gas ratios. Raman scattering spectra of DLC:Cu films studied were typical of diamond-like carbon (including the films with a high Cu atomic concentration where it was up to 60 atom % and carbon atomic concentration was less than 20 atom %). In all cases, in the absorption spectra of DLC:Cu films, the surface plasmon resonance-related peak was recorded. The position of the plasmonic peak for all the deposited nanocomposite films was in a 590–620 nm range. For the samples containing lower amounts of copper, reverse-saturable absorption was found. Transient optical absorption measurements have shown that the reverse-saturable absorption is typical for the samples with a lower relaxation time. The longer relaxation times recorded during transient optical absorption measurements correlated with the presence of the saturable absorption effect. For DLC:Cu samples containing 58–62 atom % Cu, some optical inhomogeneities were observed. The samples in different places demonstrated either saturable absorption or reverse-saturable absorption. The presence of both saturable and reverse-saturable absorption effects in the same sample is explained by the lateral inhomogeneities of the DLC:Cu films. Full article
